multi riffle design in a sluice

How To Build and Operate Sluice Boxes

multi-level boxes into the field. For fine gold recovery the use of riffles can actually be a negative design element and most boxes specifically built for this type of gold don’t use any type of riffle system.

Riffles and Sluice Boxes - How do they work?

As the flow passes over a riffle, the heavies will fall to the bottom behind a riffle. Second, the riffles are spaced a couple of inches apart, and act as a series of small dams, stopping the creep of the heavy material down the sluice. Without them, there would be a slow, but sure creep of gold out the end of the sluice.
